Ok just got my system set up. Got a taramp bass 3k. Found a really good ground under the seat. Did a clamp test and getting 50 volts and 12 amps which is about 600 watts and at this point its clipping.... measured the amp voltage at inputs and getting 12v exactly. Getting 13.9 at the battery. Haven't done the big three but plan to. What could be the issue here? Is my power cable bad? I am trying to run at 1200 watts on dual 2 ohm subs.
